Abstract :
This paper presents the application of sequential Monte Carlo (SMC) methodology for blind detection in wireless DS-CDMA systems over fading channels. A novel blind Cholesky-SMC receiver based on the techniques of Cholesky factorization and sequential importance sampling is developed for differentially encoded DS-CDMA systems. With simulated results, the promising performance of the proposed receiver is demonstrated for the both the systems over the flat fading channels and frequency-selective fading channels.
